Parameterized bipartite entanglement measure
Zhi-Wei Wei, Shao-Ming Fei
Abstract
Abstract We propose a novel parameterized entanglement measure α -concurrence for bipartite systems. By employing positive partial transposition and realignment criteria, we derive analytical lower bounds for the α -concurrence. Moreover, we calculate explicitly the analytic expressions of the α -concurrence for isotropic states and Werner states.
